Description of AC servo motor EM3G-09
EM3G-09 is a smallest AC brushless servo motor in the standard medium speed and medium inertia series. This model delivers enough high torque with a small frame size. This servo motor is supplied with high resolution absolute 23-bit optical or 17-bit magnetic encoder. Optional 24VDC brake is available.
EM3G servo motor series is designed to provide increased operating speed range without reducing output power. This feature significantly expands the range of possible usage applications and in many cases allows excluding a gearbox, improving reliability and reducing overall cost.
